NURSING-BOTTLE.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed December 17, 1904. Serial No. 237,291.

- To all whomit may concern.-

Be it known that I, HUGH F. GALLAGHER, a citizen of the United States,residing at Saltsburg, in the county of Indiana and State ofPennsylvania, have invented a new and useful Nursing-Bottle, of whichthe following is a specification.

This invention relates to nursing-bottles.

Nursing-bottles in general use all have a straight bore and rounded rim.The objections to this construction are that the air-valve that iscombined with 'most nipples now in use is mashed or bent by contact withthe upper edge or inner wall of the rim and is thus renderedinoperative, that considerable difficulty is encountered in positioningthe nipple upon the rim, and that owing to the rounded contour of therim the connection or engagement between it and the nipple is not asecure and positive one, so that disconnection between the partsfrequently ensues in use which results in the loss of the contents ofthe bottle and other objectionable features.

The objects of the present invention are to improve the neck portion ofa bottlein such manner as to facilitate the application of the nipplethereto, to render the connection between the bottle and the nipple morestable and tenacious in character, to obviate any interference betweenthe neck of the bottle and the air-valve now generally combined withnipples, and generally toimprove and render more efiicient bottles ofthe character described.

With the above and other objects in View, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction of a bottle-neck, as will be hereinafter fully describedandclaimed.

In the accompanying drawings, forming a part of this specification, andin which like characters of reference indicate corresponding parts,there is illustrated one form of embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theelements therein exhibited may be varied or changed as to shape,proportion, and exact manner of assemblage without departing from thespirit thereof.

In the drawings, Figure 1 is a view in elevation, partly in section, ofa bottle constructed in accordance with the present invention,exhibiting the construction of the mouth and the rim. Fig. 2 is afragmentary detail view in section, exhibiting the neck portion of thebottle shown in Fig.1 with the nipple applied thereto and displaying themanner in which the air-vent valve is disposed within the mouth of therim. Fig. 3 is a view similar to Fig. 2, exhibiting the ordinarybottleneck and showing wherein the valve by contact with the mouth ofthe rim is deflected, and thus rendered inoperative.

Referring to the drawings, and to Figs. 1 and 2 thereof, 1 designatesthe body of the bottle; 2, the neck; 3, the rim; and 4 the mouth. Theneck and body of the bottle may be of the usual or any preferredconstruction, the form herein shown being exhibitive of one style thatmay be employed.

The gist of the present invention resides in the novel manner ofconstructing the rim 3 and mouth 4:, whereby the connection between thenipple N and the neck will be of more positive character and whereby,further, the vent-valve n of the nipple will not be deflected or bentupon itself and thus rendered inopertive. The first function is securedby making the periphery or outer wall of the rim a truncated cone withits periphery slightly rounded, as at 4, to avoid sharp corners and anydanger of cutting the nipple, and its under side or shoulder 5 beingsquare or approximately at right angles to the longitudinal axis of theneck, whereby, as clearly shown in Fig. 2, the mouth of the nipple willbe firmly held in position against accidental separation, the pitch ofthe sides of the cone being such as to cause the nipple to clingtenaciously to the rim under any strain to which it may be subjected inuse. By having the outer Walls of the neck straight and on the lines ofa true cone the same will act as a wedge when the nipple is appliedthereto, and thereby facilitate its positioning. The second function issecured by making the mouth concaved or an inverted truncated cone,presenting thereby deflectingsurfaces against which the nipple-valve Nmay lie and which will preclude the possibility of the valve beingmashed or bent upon itself, as shown in Fig. 3, which exhibits the formof bottle neck and rim in common use.

It will be seen from the foregoing descrip-' tion that although theimprovements of this invention are simple in character they secure theresults designed in a thoroughly feasible and practical manner, and,further, that no added cost attends the manufacture of the bottle whichwould militate against its introduction.

While the improvements herein defined are described as used inconnection with nursingbottles, it is to be understood that they may beemployed in connection with any other kind of bottle where their useWould be of value, and as this Will be readily understood furtherillustration of any preferred adaptation to use is deemed unnecessary.Furthermore, While the nipple herein shoWn is of the kind embodying avalve, it is to be understood that the invention is equally adaptablefor use in connection with ordinary plain or valveless nipples, and asthis will be apparent detailed illustration of such adaptation of theinvention to other uses is thought tobe unnecessary.

Having thus described the invention, what is claimed is A bottle havinga rim triangular in crosssection, the pitch of both sides of which isthe same, and With a base disposed at right angles to the long diameterof the neck, the periphery of the base being rounded.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of tWo Witnesses.
